I purchased a set of Talley Tactical 30mm rings ($169) and a set of PRI int high rings also in 30mm, but my Mk4 low rings got here in time. They had been backordered for a cpl months. These rings, have never been out of box, much less mounted. The PRI's were $90 both purchased with C&R discount at Midwayusa. I am looking for Varget powder and 260 brass, maybe even some 123 6.5mm a max or 139 scenars. Also may trade for H4350
